To speed things up, we don't decode tags unless they're asked for. Exposes a dictionary interface of the tags in the directory:: ifd = ImageFileDirectory_v2() ifd[key] = 'Some Data' ifd.tagtype[key] = TiffTags.ASCII print(ifd[key]) 'Some Data' Individual values are returned as the strings or numbers, sequences are returned as tuples of the values. The tiff metadata type of each item is stored in a dictionary of tag types in :attr:`~PIL.TiffImagePlugin.ImageFileDirectory_v2.tagtype`. The types are read from a tiff file, guessed from the type added, or added manually. Data Structures: * ``self.tagtype = {}`` * Key: numerical TIFF tag number * Value: integer corresponding to the data type from :py:data:`.TiffTags.TYPES` .. versionadded:: 3.0.0 'Internal' data structures: * ``self._tags_v2 = {}`` * Key: numerical TIFF tag number * Value: decoded data, as tuple for multiple values * ``self._tagdata = {}`` * Key: numerical TIFF tag number * Value: undecoded byte string from file * ``self._tags_v1 = {}`` * Key: numerical TIFF tag number * Value: decoded data in the v1 format Tags will be found in the private attributes ``self._tagdata``, and in ``self._tags_v2`` once decoded. ``self.legacy_api`` is a value for internal use, and shouldn't be changed from outside code. In cooperation with :py:class:`~PIL.TiffImagePlugin.ImageFileDirectory_v1`, if ``legacy_api`` is true, then decoded tags will be populated into both ``_tags_v1`` and ``_tags_v2``. ``_tags_v2`` will be used if this IFD is used in the TIFF save routine. Tags should be read from ``_tags_v1`` if ``legacy_api == true``.
